Chrysanthemum plant named ‘Mega Time Improved’

ABSTRACT

A new variety of  Chrysanthemum  plant named ‘Mega Time Improved,’ having a flat capitulum of light pink single flowers with a dark spot in the disc.

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.

Variety denomination: The new Chrysanthemum variety denomination is ‘Mega Time Improved. ’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Chrysanthemum morifolium, and referred to by the cultivar name ‘Mega Time Improved.’

‘Mega Time Improved’ identified as 20929-0A was discovered as a whole plant natural mutation in a controlled cultivated planting of the variety ‘Mega Time,’ an unpatented seedling. The new variety ‘Mega Time Improved’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘Mega Time Improved’ is a pot type of Chrysanthemum plant variety having a flat capitulum of light pink single flowers with a dark spot in the disc.

Comparison With Parent

Plants of the new Chrysanthemum variety ‘Mega Time Improved’ are similar to the parent variety ‘Mega Time’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Mega Time Improved’ compared to plants of the parent ‘Mega Time’ in the following characteristics:

-   -   1. The new variety ‘Mega Time Improved’ produces light pink         single flowers whereas the parent ‘Mega Time’ also produces         light pink single flowers.     -   2. Plants of the new variety ‘Mega Time Improved’ have similar         inflorescence to plants of the parent ‘Mega Time.’     -   3. Plants of the new variety ‘Mega Time Improved’ have a slower         response time than the plants of the parent ‘Mega Time.’     -   4. Plants of the new variety ‘Mega Time Improved’ have a shorter         vigor when compared to the plants of ‘Mega Time.’

Comparison with Other Varieties

Plants of the new Chrysanthemum variety ‘Mega Time Improved’ are dissimilar to the variety ‘Elgon Light Pink’ (United States Plant Patent Pending) in plant habitat and growth rate. However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Mega Time Improved’ differed from plants of the variety ‘Elgon Light Pink’ in the following characteristics:

-   -   1. The new variety ‘Mega Time Improved’ produces light pink         single flowers with a dark spot in the disc whereas the variety         ‘Elgon Light Pink’ produces light pink single flowers.     -   2. Plants of the new variety ‘Mega Time Improved’ have larger         and taller inflorescence than plants of ‘Mega Time Improved.’     -   3. The new variety ‘Mega Time Improved’ has a slower response         time than the plants of ‘Elgon Light Pink.’

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Mega Time Improved’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of April. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of about 5,000 to 6,000 foot candles. The plants respond well to the use of growth retardant, such as one B9 treatment at about 2 gram per liter. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 liter. It has been observed that the shelf life of the new variety is about 28 days with a response time of about 8 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

The new variety may be produced as a spray or disbud. The following description is with respect to a plant produced as pot. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
